5.2 Release Notes

eZ Publish 5.2 is a point release towards 5.3 LTS which enhances several aspects of the 5.x kernel for usability and extensibility, it serves as the foundation for 5.3.

Meet the updated eZ Publish 5.2

Context-aware HTTP cache with UserHash

With eZ Publish 5.2, new stack's HTTP cache is finally on par and beyond what was possible in eZ Publish legacy. With UserHash, by default all internal controllers, including the ViewController, will return cacheable responses, based on user access rules. This behavior is also applicable to custom controllers by making their response vary on X-User-Hash header. Moreover, UserHash generation, initially based on current user's assigned roles and policies, is extensible.

Purging is furthermore done in a stale cache like way, making sure stale cache gets served while the new one is being generated. Stress tests on 5.2 have shown noticeable performance improvements thanks to the introduction of UserHash.

Symfony 2.3

Updated our web framework foundation to Symfony 2.3 LTS, more info on this release can be found here.

Custom controllers for content view

Have you ever been missing a way to extend the provided content controller? Had needs to do custom cache logic and been missing the good old cache_ttl = 0 hack?
5.2 brings with it a powerful way to use the existing override system to, instead of overriding just a template, override the whole controller. This allows you to extend the built-in controller and for instance get full access to tune the cache headers for a specific content type that has different use than normal content, or just enrich the final template.

Signal slot events

Signal slot events are now fully listenable, which makes it possible to react on core API signals. These events are now also dispatched over Symfony's event system so you can listen to them there synchronously, while custom slots (listeners for signals) can in the future be dispatched asynchronously. 

This enhancement makes it possible to define micro-workflows.

Multi repository cache support

This release resolves a limitation with persistence caching introduced in 5.1, a new caching service "ezpublish.cache_pool" takes a siteaccess group setting "cache_pool" into consideration for selecting cache service, and hence can be configured with multi repository setups in mind. In addition you can now safely reuse this cache pool as the persistence cache is prefixed within "spi" cache key and will not clear your data if you reuse it.

Support for more than 30 languages

With 64-bits servers now being common, this release takes advantage of that if present and provides support for up to 62 languages on 64-bits environments and 30 languages on 32-bits platforms. This feature is supported across both Symfony stack and legacy stack, and is accomplished by increasing the size of the integer field used for language bit masks. Improved storage engines still has the possibility to provide even more languages on pure Symfony stack in the future.
